Worksheet showing the evolution of transport from past to present.

Problem Description:

The task is to choose a modern mode of transport and illustrate how it has changed over time by drawing three pictures. The worksheet provides a timeline with "Past" on the left and "Present" on the right, indicating that the changes should be depicted in chronological order.

Solution Approach:

1. Choose a Mode of Transport: Select a modern mode of transport that has evolved significantly over time. For this example, let's choose cars.
2. Understand the Evolution: Research or recall how cars have changed from the past to the present.
3. Draw Three Illustrations:
- Past: Draw an early model of a car (e.g., a horseless carriage or early 20th-century car).
- Middle: Draw a mid-20th-century car to show intermediate developments.
- Present: Draw a modern car with contemporary features.

Step-by-Step Solution:

#### 1. Past (Early Car)
- Description: In the early days of automobiles (late 19th to early 20th century), cars were simple and rudimentary. They often had open tops, exposed engines, and basic mechanical systems.
- Drawing: Sketch a car with a boxy body, large wheels, an open top, and visible engine components. Include details like a simple steering wheel and minimal interior features.

#### 2. Middle (Mid-20th Century Car)
- Description: By the mid-20th century (around the 1950s–1960s), cars became more streamlined and comfortable. Features like enclosed bodies, better suspension, and improved safety began to emerge.
- Drawing: Sketch a car with a sleeker design, rounded edges, and a closed roof. Include features like side mirrors, larger windows, and a more advanced dashboard.

#### 3. Present (Modern Car)
- Description: Modern cars are highly advanced, featuring electric/hybrid engines, autonomous driving capabilities, and extensive use of technology for comfort and safety.
- Drawing: Sketch a contemporary car with aerodynamic lines, LED headlights, and a sophisticated dashboard. Include features like touchscreens, GPS navigation, and possibly self-driving elements.

Final Answer:

The three illustrations should depict:
1. Past: An early car with an open top, exposed engine, and basic design.
2. Middle: A mid-20th-century car with a streamlined body, enclosed roof, and improved features.
3. Present: A modern car with advanced technology, aerodynamic design, and luxury features.

Visual Representation:

While I cannot draw images here, the descriptions above provide clear guidance on what each illustration should look like. Students can use these instructions to create their own drawings.

Final Answer:
\boxed{\text{Draw an early car, a mid-20th-century car, and a modern car to illustrate the evolution of transportation.}}
